Changes between Initial Version and Version 1 of Ticket #62272, comment 1

-                      initial
+                      v1
 The error seems to be in `wp_check_filetype_and_ext()`. It [https://core.trac.wordpress.org/browser/trunk/src/wp-includes/functions.php#L3151 uses] `finfo_file()` to get the `$real_mime` which is returned as `image/heif`. However that mime type is treated as unsupported, only `image/heic` is supported.
+Seems the fix can be as easy as mapping `image/heif` to `image/heic` in `wp_check_filetype_and_ext()`. However wondering if adding `image/heif` to the supported image mime types may be a better idea?
